Stable Au25(SR)18/TiO2 Composite Nanostructure with Enhanced Visible Light Photocatalytic Activity
Abstract
We report the visible light photocatalytic properties of a composite material consisting of Au 25 (SR) 18 nanoclusters (R:CH 2 CH 2 Ph) and TiO 2 nanocrystals. The effects of Au 25 (SR) 18 nanoclusters on the photocatalytic activity of TiO 2 nanocrystals were evaluated in the reaction of photocatalytic degradation of methyl orange. The loading of Au 25 (SR) 18 nanoclusters onto TiO 2 results in strong visible light absorption by the composite and, more importantly, a 1.6 times increase in visible light photocatalytic activity. Furthermore, the Au 25 (SR) 18 /TiO 2 composite nanostructure exhibits high stability in recycling tests. The Au 25 (SR) 18 nanolusters dispersed on the TiO 2 surface can act as a small-band-gap semiconductor to absorb visible light, giving rise to electron–hole separation and producing singlet oxygen ( 1 O 2 ). Both the generated hydroxyl radicals (HO • ) and 1 O 2 are rationalized to be responsible for the decomposition of the dye.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
